Successful pregnancy in one horn of a bicornuate uterus

Abstract

Normal development of the female reproductive tract involves a series of complex processes characterized by the differentiation, migration, fusion, and subsequent canalization of the Müllerian system. Uterine anomalies result when these processes are interrupted. Bicornuate uterus is a unification defect of the Müllerian ducts, and it is estimated to represent 10-39% of Müllerian duct anomalies. Pregnancies in bicornuate uterus are usually considered high-risk because of association with poor reproductive outcomes, such as pregnancy loss, preterm birth, malpresentations, and fetal deformity. Routine cervical cerclage and Strassman metroplasty have been advocated as treatment for this anomaly. We report a case of successful pregnancy in one of the horns of a bicornuate uterus managed in our unit.
